    public class WideLaneCombination
    extends AbstractDualFrequencyCombination
    Wide-Lane combination.

    This combination are used to create a signal with a significantly wide wavelength. This longer wavelength is useful for cycle-slips detection and ambiguity fixing

                  f1 * m1 - f2 * m2
        mWL =  -----------------------
                       f1 - f2
     
    With:
    • mWL: Wide-laning measurement.
    • f1 : Frequency of the first measurement.
    • m1 : First measurement.
    • f2 : Frequency of the second measurement.
    • m1 : Second measurement.

    Wide-Lane combination is a dual frequency combination. The two measurements shall have different frequencies but they must have the same MeasurementType.
